They are expensive, ranging from $150-200 per treatment, but they last for up to three months, perfect for getting you through a holiday season full of parties, for example, or a hot, humid summer. If you're trying to nail a polish that actually stays on after you leave the manicurist, try a gel manicure. Gel manicures use special polishes that are "cured" under UV lights and dry super fast, getting you in and out of the salon smudge-free and fast. And finally, if hair removal is a hairy situation, stop spending your hard-earned cash on cans of shaving cream, fancy razors and depilatories. Laser hair removal is performed by dermatologists and medical spas and can run up to $150 per session, with many people needing up to five sessions for complete results. But with Groupon deals and other local specials, you can get laser hair removal for a steal - and be done with shaving for good!
